SYNOPSIS

   encfsctl [command command_args]

   encfsctl rootdir

   encfsctl info rootdir

   encfsctl passwd rootdir

   encfsctl showcruft rootdir

   encfsctl decode [--extpass=prog] rootdir [encoded name ...]

   encfsctl encode [--extpass=prog] rootdir [plaintext name ...]

DESCRIPTION

   encfsctl is an administrative tool for working with EncFS filesystems.
   It is capable of changing the user supplied password, displaying basic
   information about an encrypted volume, and other related operations.

COMMANDS

   info
       Display basic information about the filesystem.  Takes a single
       argument, rootdir, which is the root directory of the encrypted
       filesystem.  The filesystem need not be mounted.  Info is also the
       default command if only a root directory is provided on the command
       line.

   passwd
       Allows changing the password of the encrypted filesystem.  The user
       will be prompted for the existing password and the new password.

   showcruft
       Recursively search through the entire volume and display all files
       which are not decodable (only checks filename encoding, not block
       MAC headers).  This might be useful for cleanup in case you've made
       use of features which create files which are not decodable under
       the primary key.

   decode
       Allows you to specify an encoded name on the command line, and
       displays decoded version.  This is mostly useful for debugging, as
       debug messages always display encrypted filenames (to avoid leaking
       sensitive data through the debug channels).  So this command
       provides a way to decode the filenames.

       The --extpass option can be used to specify the program which
       returns the password - just like with encfs.

       If no names are specified on the command line, then a list of
       filenames will be read from stdin and decoded.

   encode
       Allows you to specify a filename on the command line, and displays
       its encoded version. This is useful if e.g. you are taking a backup
       of an encrypted directory and would like to exclude some files.

       The --extpass option can be used to specify the program which
       returns the password - just like with encfs.

       If no names are specified on the command line, then a list of
       filenames will be read from stdin and encoded.

EXAMPLES

   Show information about an encrypted filesystem:

    % encfsctl info ~/.crypt

    Version 5 configuration; created by EncFS 1.1 (revision 20040504)
    Filesystem cipher: "ssl/aes" , version 2:1:1
    Filename encoding: "nameio/block" , version 3:0:1
    Key Size: 192 bits
    Block Size: 512 bytes
    Each file contains 8 byte header with unique IV data.
    Filesname encoded using IV chaining mode.
